Surgical mesh fabric

Abstract

A dual bar warp knit, hexagonal mesh fabric for use in hernia repair and to mend other muscle and tissue wall defects, produced according to a back bar pattern chain of 2/0 2/4 2/0 4/6 4/6 and a front bar pattern chain of 4/6 4/2 4/6 2/0 2/4 2/0.

What is claimed is: 
     
       1. As a prosthetic for repairing living animal tissue, body wall or muscle defects, a biologically compatible, implantable dual bar warp knit, hexagonal mesh produced according to a back bar pattern chain of 2/0 2/4 2/0 4/6 4/2 4/6 and a front bar pattern chain of 4/6 4/2 4/6 2/0 2/4 2/0. 
     
     
       2. The implantable dual bar warp knit, hexagonal mesh recited in claim 1 formed of polypropylene monofilament yarns. 
     
     
       3. The implantable dual bar warp knit, hexagonal mesh recited in claim 1 including a body portion and a selvage that is more rigid than said body portion. 
     
     
       4. The implantable dual bar warp knit, hexagonal mesh recited in claim 1 wherein said more rigid selvage is curled. 
     
     
       5. The implantable dual bar warp knit, hexagonal mesh recited in claim 1 including elongated diamond to square pores. 
     
     
       6. The implantable dual bar warp knit, hexagonal mesh recited in claim 1 including circular pores. 
     
     
       7. The implantable dual bar warp knit, hexagonal mesh recited in claim 1 including near circular pores. 
     
     
       8. The implantable dual bar warp knit, hexagonal mesh recited in claim 1 including square pores. 
     
     
       9. The implantable dual bar warp knit, hexagonal mesh recited in claim 1 including diamond pores. 
     
     
       10. The implantable dual bar warp knit, hexagonal mesh recited in claim 1 including yarn columns formed by two separate ends of yarn that cross each other on two needles with the crossover portion traversing across a third needle, wherein in one end of yarn breaks a back up yarn will secure the fabric from at least two yarns way to prevent unraveling of the mesh. 
     
     
       11. The implantable dual bar warp knit, hexagonal mesh recited in claim 1 wherein said mesh is supported within a laparoscopic cannula.
